Faulty digital first response

Hello. I am around 4 to 5 weeks pregnant and I have had a chemical before. My line progression this time has been amazing. I took a test last night and the test line was way darker than the control line. Then today I had one last test and was like okay I will just take it and get my mind off of testing. So I unwrapped the digital and the screen was blank and continued to be blank. After about 5 mins I was like eh okay maybe if i dip it itll wake up. I did and nothing. So finally i cracked it open to see what was going on and then it turned on. So i closed it back up and let it do its thing since it was working all the sudden. Eventually it came back no.... now im freaking out that i am having another chemical. Has anyone had similar situations?
